ISPConfig Server move

In the next few days I need to move servers! I don't have a huge number of accounts set up, so it shouldn't be too bad...

The server I've moving off has ISPConfig version 2.2.15, and I'm moving to a server with ISPConfig 2.2.19.

Obviously I can manually dump the ISPConfig database and restore it on the new machine, and copy all the sites across via scp, but I noticed a couple of backup options within ISPConfig, but didn't see a restore option!
